Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163984, here are decompositions:
- 3 + 163981 = 163984
- 5 + 163979 = 163984
- 11 + 163973 = 163984
- 83 + 163901 = 163984
- 101 + 163883 = 163984
- 113 + 163871 = 163984
- 131 + 163853 = 163984
- 137 + 163847 = 163984
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 163,984 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 163984 first appears in π at position 826,573 of the decimal expansion (the 826,573ordinal-suffix:rd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
